This paper reports on research to investigate design features of asynchronous discussion systems for higher education. The research aims to identify features that increase the benefits of discussion systems and reduce the problems. The paper focuses on a major theme that emerged from interviews with learners and teachers: information overload.…

The SAGRES system is an educational environment built on the Web that facilitates the organization of visits to museums, presenting museum information bases in a way adapted to the user's characteristics (capacities and preferences). The system determines the group of links appropriate to the user(s) and shows them in a resultant HTML page. In…

Describes page structure models for the design of electronic books. Approaches to electronic book design are discussed, including CD-ROM, multimedia, and hypermedia; information delivery techniques in electronic books are discussed; and three case studies are reviewed: screen design for computer-based training, interactive guidebooks, and…

When students feel that their learning needs are not being met by computer-aided instruction, learning becomes passive, often resulting in boredom, frustration or a dislike for learning with computers. "Button Theory" allows the student to express his feelings and questions to the computer at the touch of a button, thus enhancing control over the…

Reviews the historical development and technological features of hypertext, a computerized nonlinear text system. Three major areas of applications are identified: (1) instruction, (2) electronic publishing and online databases, and (3) thinking and authoring tools. Research issues in document processing and education are also discussed. (28…

This paper focuses on issues of representation and interaction styles that are relevant considerations in the design and analysis of hypermedia learning environments. Analysis is supported by examples from the "HUGH" series of studies involving learners in reasoning about formal hypermedia representations. The representational issues include…

This paper describes the use of the CoFIND (Collaborative Filter in N Dimensions) system to evaluate two assessment styles. CoFIND is a resource database that organizes itself around its users' needs. Learners enter resources, categorize, then rate them using "qualities," aspects of resources which learners find worthwhile, the n…

The Magazine and Journal Instructional Kit (MAJIK/1) is a HyperCard program delivering basic individualized library instruction. Using a technique derived from naturalistic inquiry, the program's formative evaluation was conducted at the University of Maryland, College Park, with 28 upperclassmen as subjects. They reported little difficulty with…

Computer assisted language learning (CALL) packages offer the majority of students who are learning English as a foreign language the opportunity for individual instruction. To meet the needs of an individual student, an adaptive CALL environment must have a dynamic model of student performance, a means of varying the difficulty of the learning…

Describes the design, development, and evaluation of an electronic mail system, the Instructional Support Network, for use in continuing education correspondence courses at the U.S. Naval Postgraduate School. Computer networks are discussed, hardware and software are described, and problems with the system are considered. (16 references) (LRW)

This study of 40 undergraduates examined whether aiding as cognitive support (i.e., offering computer users knowledge they are missing) can supplement lack of knowledge and capacity under tasks with high mental loading, such as dealing with irregularities in process control. Users of a railway traffic control simulator dealt better and faster with…

Describes the design of an electronic performance support system (PSS) that was developed to help sales and support personnel access relevant information needed for good job performance. Highlights include expert systems, databases, interactive video discs, formatting information online, information retrieval techniques, HyperCard, computer-based…

This project was designed to provide a framework for user evaluation of software packages and hypertext environments in terms of the extent to which they provide flexibility for learners to follow their preferred learning styles. Evaluation was carried out in relation to hypertext packages, learning styles and outcomes, and system design. (four…
